Can't quite see which paw that is. If it is his front right paw then yes Gandolf RIP used to sleep like that and I thought it odd at the time. In fact he also used to sleep with his jaw flat out ahead of him and both left and right paws stretched out behind him with paw pads facing upwards if you follow my meaning. He only did this in later life (say age 15 and after) and I always assumed it was linked to getting comfortable with elderly aches and pains. How old is Zak? (I just know you're going to say he's a young un!)
